PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 639,802, dated December26, 1899. Application filed June 20, 1894. Renewed May 27, 1899. SerialNo. 718,536. (No model.)

To all whom it may concern:

Be it known that I, HENRY A. Wish: W001), a citizen of the UnitedStates, residing at New York, in the county of New York and State of NewYork, have invented a new and useful Improvement in Printing-Machines,of which the following is a specification.

My invention relates to that class of printing-machines which are knownas travelingcylinder web-printing presses; and the object of myinvention is to provide an improved construction in which the web willhave a very simple and direct path of travel in such position that itwill leave at least one of the type-forms so that the same will bereadily accessible.

To these ends my invention consists in the parts and combinations ofparts,'as hereinafter described, and more particularly pointed out inthe claims at the end of this specification. 1

In the accompanying two sheets of drawings, Figure 1 is a side elevationof a printingmachine constructed according to my invention, and Fig. 2is -a diagrammatic sectional view of the same.

Referring to the drawings and in detail, 0 designates the firstimpression-cylinder,which cooperates with a stationary form-bed A, and Ddesignates the second impression-cylinder, which cooperates with asimilar stationary form-bed B. The impression-cylinders O and D arejournaled in a suitable framing or carriage E, which is guided uponsuitable ways carried by the side frames of the press.

At each side of each of the impression-cylinders I provide suitableform-inking rollers F, which cooperate with a suitable ink-distributingapparatus I in order to properly ink the forms upon the stationaryform-beds A and B.

Journaled in the side frames 10 at one end of the press I provide aweb-roll W, from which the paper is led into the press between theconstantly-running feeding-in tapes and 16. The endless tapes 15 passover suit able tape-rollers 11 and l3,and similar endless tapes 16 passover the tape-rollers 12 and 14,

the tapes being driven or actuated as hereinafter described.

As shown in the drawings, it will be seen that the web is led into thepress so that the feeding-in devices are located below one of thestationary form-beds. I con sider this arrangement desirable, as itenables me to econ omize space and to form a compact machine, and byintroducing the web into the press between the two stationary beds, aswill be hereinafter explained, it will be seen that I am enabled todeliver the web directly from one end of the press.

From the constantlyrunning feeding-in tapes the web passes down underthe loopingin roller 17, between the stationary form-beds, up and arounda guide-roller 18, journaled in the side frames of the press, over andaround a guide-roller 19, journaled in the cylindercarriage, down underand around the first impressioncylinder 0, over and around aguide-roller 20, also journaled in the cylindercarriage, over and arounda guide-roller 21, journaled in the cylinder-carriage, over and aroundan adjustable register-roll 22, journaled in the side frames of thepress, over a guide-roller 23, j ournaled in the cylinder-carriage atone side of the second impressioncylinder D, down under and around theimpression-cylinder D, over and around a guideroller 24 at the oppositeside of the impression-cylinder D, under and around a guideroller 25,journaled in the side frames, over the looping-out roller 26, and overand around the constantly-running feeding-out roller 27. As shown in thedrawings, the feeding-out roller 27 cooperates with suitable endlesstapes 32, the tapes 32 being led over suitable tape pulleys or rollers28, 30, and 31,as shown. By providing this path of travel of the web itwill be seen that the impression-cylinder C will be mounted,substantially, in a loop of the web, (as the roller could be omitted, ifso desired,) and it will also be seen that when the impression-cylinder0 travels to the right, as considered in the drawings, this loop of theweb will be given up, and the web would become slack if it were not forthe roller 21,

which forms a loop in the web and takes up the same as fast as it isgiven out on account of the motion of the impression-cylinder O, or, inother words, the impression-cylinder O and the roller 21, which movessynchronously therewith, form a loop in the web, which may be shiftedback and forth without slackening the web or affecting the feeding-inand delivery ends thereof, and by this construction it will be seen thatwhen the impression-cylinder C is at the right-hand end of its travel,as shown in the drawings, the web will be shifted from over the form-bedA,which leaves the form-bed easily accessible, so that the forms can besecured in place thereon. I consider this construction a feature ofimportance, as in the ordinary forms of travelingcylinderprinting-presses the web is led over the form-beds in such position asto practically prevent access thereto, and in using this form of pressit has heretofore been customary to secure the forms in place after theweb is threaded through the machine, which results in considerable delayin the printing owing to the difficulty in properly securing the formson the bed. This class of presses is of course ordinarily employed inprinting newspapers, and in my construction one of the forms, which maybe set up from standard matter, is secured in place upon the formbed B.

The web is threaded through the machine, the form to be secured upon thebed A being kept open until the last minute, the last operation beforeprinting being simply. to secure this form in place upon its bed A,which can be almost instantly done, and I am enabled to commence theprinting at once when the form has been secured in place, which ofcourse is a feature of importance in newspaper-work, and of course thissame saving is made where a number of forms are placed abreast on eachbed.

The gearing for driving the press may be arranged in any of the ordinaryor preferred manners. As shown in the drawings, 33 designates apower-shaft, to which power may be applied in any of the ordinary orpreferred manners. Fastened upon and turning with the power-shaft 33 Iprovide gears 34, which mesh with and actuate the driving-gears 35,which are secured upon a shaft 36. Suitable crank-pins carried by thedriving-gears 35 are connected by pitmen 37 and actuate levers 38, whichare secured to the cross-shaft 39 The levers 38 are connected with anddrive the cylinder-carriage E by means of suitable pitmen 40, as shown.The constantly-running feeding-in tapes may, if desired, be driven fromone of the driving-gears 35 by means of a pinion 61, which meshes withand drives a gear 62, fastened to the tape-roller 14, the gear 62 inturn meshing with and driving a gear 63, secured to the tape-roller 13.Actuated and driven from the power-shaft 33 by means of bevel-gears 41and 42 I provide a horizontal shaft 43. Secured to the horizontal shaft43 I provide a bevel-pinion 44, which meshes with and drives abevel-gear 45, having a spur-gear 46 secured thereto, which meshes withand drives a gear 47 for actuating the cam-shaft 48, journaled in theside frames of the press, as shown. Fastened upon and secured to thecam-shaft 48 are suitable cams 47, which actuate rollers journaled uponsuitable levers 50, as shown. The levers 50 are connected by suitablepit men 51 with bell-crank levers 52, which actuate the looping-inroller 17 by means of pitmen 53, and to bell-crank levers 54, whichactuate the looping-out roller 26 by means of pitmen 55. Actuated anddriven from the horizontal shaft .43 by means of bevel-gears 56 and 57 Iprovide a vertical shaft 58, which in turnactuates and drives theconstantlyrnnning feeding-out roller 27 by means of the bevel-gears 59and 60. It is evident, 110wever, that many different arrangements ofgearing or driving mechanism can be adopted without departing from thespirit of my invention,whicl1 relates particularly to the path of theweb through the machine, and I am aware that many changes may be made bythose who are skilled in the art without departing from the scope of myinvention as expressed in the claims.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

l. The combination with two form-beds, a traveling impression cylindercooperating with each form-bed, web-guides adapted to lead the web tothe first impression-cylinder, a looping-roller moving with theimpressioncylinders, to which the web passes from the first impressioncylinder, a stationary roll around which the web then passes to thesecond impression-cylinder, and a web manipulating or feeding mechanism,substantially as described.

2. The combination of two form-beds arranged in substantially the samehorizontal plane, a traveling impression-cylinder cooperating with eachform-bed, means for leading the web into the machine up between theform-beds, a looping-roller moving with the impression-cylinders towhich the web passes from the first impression-cylinder, and aroundwhich the same is looped between the two impression -cylinders, astationary roll interposed between the looping-roller and the secondimpression-cylinder, and a web manipulating or feeding mechanism,substantially as described.

3. The combination in a printing-press of two form-beds, a travelingimpression-cylinder coacting with each form-bed, web-guides comprisingweb-guides on the frame, a looping-roller moving with theimpression-cylinders interposed in the path of the web be tween the twoimpression-cylinders, and a stationary r011 interposed in the path ofthe web between the looping-roller and the second impression-cylinder,means for adjusting this last-named roll whereby the same may act as aregister-adjusting device, and a web manipulating or feeding mechanism,substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing 10 witnesses.
